The concept is that, through thought alone, a person could direct a robotic arm â€“ a neural prosthesis â€“ to reach and manipulate a desired object.
As a step toward that goal, University of Pittsburgh researchers report that a monkey outfitted with a child-sized robotic arm controlled directly by its own brain signals is able to feed itself chunks of fruits and vegetables. The researchers trained the monkey to feed itself by using signals from its brain that are passed through tiny electrodes, thinner than a human hair, and fed into a specially designed algorithm that tells the arm how to move.
Um... Holy crap!
Next thing you know, they'll have frickin' LASER beams mounted to their skulls!
